The correspondent of the Philadelphia Press with Gen.
McClellan’s army says:
“In one of the brigades of the Union army they have six guns
of a new construction, and terribly effective.
We have not yet learned their names.
The men designate them ‘coffee mills.’
It is a heavy rifle barrel mounted on wheels. At the breach is a kind of clock-work
machinery, surrounded by a hopper similar to the hopper of a coffee mill, at
the side is a crank.
One man turns the crank, while another supplies the
cartridges, and a third sights the gun.
By means of a leaver he moves it laterally, or raises or depresses it at
pleasure. Its effective range is 1¼ miles. It throws 240 balls per minute, the size of
an ordinary minié ball. When operated with, the rebels were utterly
amazed, not knowing what to make of them.
One of these guns properly worked, and well supplied with cartridges, is
estimated to equal about 300 men.”
